7 Claims. `l

The present invention relates to an adjustable metallic wrist band for a watch or the like Wherein the parts are readily connected and disconnected by a relative endwise movement.

The band of the present invention contemplates two separable parts which are connectible and disconnectible by relative endwise movement, with one part formed with a hood to receive the other part, and with means effective within the hood for connecting said parts together.

An object of the present invention is to provide an adjustable metallic wrist band `of separable parts which may be readily connected and disconnected.

Another object of the present invention is to provide a two-part metallic wrist band in which one part is provided with a locking tongue or member for locking engagement with apertures or recess means in the other part, the parts being connected by simple push action and disconnected by lifting movement of the tongue.

A still further object of the present invention is to provide a two-part metallic wrist band with one part carrying a resilient locking tongue engageable with transverse slots in the other part.

The invention has for an additional object the provision of an adjustable metallic wrist band comprising two separable parts one of which carries a tongue engageable with apertures in the other part.

Another and still further object of the present invention is to provide an adjustable metallic wrist band of two separable parts, one part having a tongue engageable with notches in the other part.

A yet further object of the present invention is to provide an adjustable metallic Wristband of two parts, one part having a hood enterable by the other part, the hood being provided with a resilient detent-carrying portion which is movable to unlock the parts.

A further object of the present invention is to provide an adjustable metallic wrist band economical to construct and assemble and which is composed of parts readily made by machinery.

Generally speaking one part of the wrist band is formed with a hood having a cover capable of resilient or hinging movement, which cover carries detent means engageable with suitably shaped recess or aperture means formed in the other part for locking the parts together when said other part has been inserted in the hood.

Embodiments of the present invention are illustrated in the accompanying drawing and the views thereof are as follows:

Figureg is a similar view showing the coacting band part provided with a plurality of circular holes; and

Figure 10 is a fragmental plan View of a coacting band part provided with side notches.

The drawing will now be explained.

Referring to Figure 1 an adjustable metallic wrist band of the present invention comprising parts l5 and I6 is shown a-s fastened to a wrist watch l1, with the parts I5 and I6 in connected relationship. y

Referring to Figures 1 and 4, a portion of the part l5 of the band, indicated as lying between the line designated by reference characters Ia and I8, is shown as down and inturned, forming anges i9 and 20 which are spaced from the adjacent part l5. The ilanges are substantially coextensive with the length of the portion between the reference characters 18a and I8.

A cover or resilient tongue 2| has one end inturned at,22 which inturned end is entered underneath the flanges I9 and 20, at one end of the portion 18a-I8 to connect the cover or resilient tongue in position to cooperate with the flanges to form a hood.

It will be noted that the side margins of the cover 2| are thickened to rest against the flanges, a-s may be observed in Figures 4, 5 and 6.

A portion of the opposite end of the cover member 2| is inturned at 23 with the inturned portion pressed tightly against the inner surface of the cover as may be readily observed in Figure 3. The inturned portion 23 is provided with detent means.

For convenience, the end of the cover 2| carrying the inturned portion 22 which secures the cover to the part I5, will be referred to as a hinged end, while the other end of the cover will be referred to as the free end.

In as-sembling the parts the fit between the inturned part 22 of the cover 2| and the `flanges I9 and 2|) is such as to securely fasten the cover in place against displacement.

Due to the curvature of the parts I5 and I6, the cover 2| is correspondingly curved, as may be observed in Figure 3, `.which rigidies the cover and aids in retaining it in place to complete the hood.

The part I6 ofthe band has a portion identified in Figure 8 as 24 for entrance into the hood to connect the band parts together. This portion 24 of the part I6 is provided with a plurality of transversely extending slots 2'5, there being a suihcient number of slots to accommodate the wrist band to wrists of different sizes.

For cooperating with the transverse slots of the portion 24 of the band part I6, detent means are provided. Figure 4 shows a detent 26 as a transversely extending deflected portion of the inturned part 23 of the free end of the cover 2 I. The length of the detent is slightly less vthan the length of the slots 25.

The portion 24 of the part I6 is inserted in the hood of the part I5 by a push action and is pushed into the hood until the wrist band is comfortably tight on the wrist of the wearer whereupon the detent 26 will clamp into one of the transverse slot-s 25 and lock the parts together. During the push action the detent means 26 will ride over the notches in the portion 24, as they cover is capable of resilient or hinging movement with respect to its hinged ends.

Referring to Figure 4 it will be noted that the portion 24 is inserted underneath the flanges I9 and 2Il. The con-struction is such that when the parts are connected as described, very little if any relative swinging movement takes place between the connected parts.

Figure 9 shows a portion 21 of the parts I6 as provided with a plurality of circular holes 28. Where the part IB -is provided with the portion 21, the inturned part 23a of the cover 2| will be provided with a cylindrical detent 29, the detent 29 engaging any one of the holes 28 when the band is tted to the wrist of the wearer.

In thi-s form of the invention the parts I5 and I6 are connected by a simple push action and are disconnected by lifting the free end of the cover 2| to disengage the detent 29l from its engaged hole 28.

Referring to Figures 6 and 10, the portion 30 of the part I B is provided with notches 3|1 formed in the side margins withv a notch on one side in register with a notch onv the opposite side.

For cooperating with the notches 3-I the inturned end 2-3b of' thecover 2| is formed with laterally spaced lugs. 32 and 33, the lugs 32 and 33 engaging with any oppositely disposed pair of notches 3| of the portion 30 insertedin the hood.

It will be noted that all of the portions of the part I6, which enter the hood, enter between the flanges I9 and 2|! of the part I5. The proportions of the detent means and the recess or aperture means are such as to lock the parts I5 and I6 together without appreciable relative movement- The fact that the portions 24, 21 and 30 enter underneath the flanges I9 and 20 prevents relative sidewise movement of the connected parts I5 and I6.

Whenever it is desired to remove the band from a wrist, the free end of the cover or resilient tongue 2| is lifted by inserting a fingernail under this end lifting it a sufcient distance to disengage the detent means with the recess or aperture means of the cooperating band part.

Because of the construction described and illustrated, the resilient tongue or cover 2| exactly conforms to the contour of the flanges I9 and 2IJ without presenting any evidence of the fact that the tongue or cover is relatively movable with respect to the part I5.

The extremities of the band parts I5 and I6 are provided with eyes 34 and 35 to receive the usual pins for fastening the wrist watch II to the band parts.

It will be observed that the wrist band of the present invention is one in which the several parts may be readily manufactured and shaped by machinery, the only assembly operation being that of applying the resilient tongue or cover 2| in place on the part I5 as illustrated in Figure 3.

Because of the construction and design of the parts entering into the present invention, it is possible to make the metallic wrist band of relatively thin material, so that its weight will not The invention has been described herein more or less precisely as -to details, yet it is to be understood that the invention is not to be limited thereby, as changes may be made in the arrangement and proportion of parts, and equivalents may be substituted, without departing from the spirit and scope of the invention.
